' To all whom it may concern:

Be it known thatrwe, RICHARD D. WIN? SHIP and PHILIP E. SMITH, citizensof the United States, residing at Chicago, in the county of Cook'and-State of Illinois, have invented certain new and useful Improvementsin Processes of Making Compos 1t1on Butter, of which the following is aspecification.

Our invention relates to a process for making composition butter; theobject of the invention is to make a composition butter of cheapermaterial than usually employed for thepurpose, which is wholesome, agreeable to taste, and naturally the color and appearance of the purebutter.

'In carrying our process into effect, we take equal parts, by weight, ofa good quality of pure butter, or butter made from cream,'and sweetmilk, or cream; to this we add substantially as much of a neutralvegetableoil, such as cotton-seed oil, by weight, as there is of eitherbutter or cream. After these three ingredients substantially in equalportions by weight have been put together, we then heat the ingredientsto a temperature between 80 and 90 degrees F., and place them in a churnand violently agitate them and while being agitated, introduce air intothe compound in a continuous stream. The air, in its passage through theagitated mass, tends to assist in the-commingling and uniting of theingredients. A portion of the air will escape from the agitated mixtureand will carry off any disagreeable, delete'rious; or noxious qualitiesor fumes that may be present in the materials, thus purifying andsweetening the product. A portion of the air will be entrapped and heldin the compound, the surface tension of the fatty substances serving toretain it in proper quantities.

The substances are broken up by the violent agitation, and everyparticle thereof is exposed to the action of the air. All of theingredients unite, forming innumerable globules thoroughly aerated, andso associated and comminuted as to form a mass of uniform color andconsistency, in appearance and taste simulating the best of pure butter.4

A churn well adapted for carrying our process into effect is disclosedin U. S. Patent No. 932,221, dated August 24th, 1909, to' Richard D.Winship.

Having thus described our invention, what we claim-is;

The process of making a composition but- .ter which consists in mixingequal quantities by weight of sweet milk or cream, pure fresh butter,and a neutral vegetable oil, heating said mixture to a temperaturebetween 80 and 90 degrees F.; thereafter placing the heated mixture in achurn and agitating said mixture; simultaneously aerating said agitatedmixture with air, at atmospheric temperature, by forcibly introducingittherein in quantities proportional to the A'elocity of the agitatingmeans, so that said air shall in some'degreevpass through said mixtureto carry off noxious qualities and fumes, and in some degree remainentrapped in the compound by the surfacev tension of said vegetable-oil;and continuing said aeration until said compound has been reduced intemperature to normal at mospheric temperature by contact of all partsthereof with said air.
